The brightest bulb this size. For its smaller physical size (smaller size than original 912/921), this Super Bright 5630 SMD LED bulb packs a punch. It has a full aluminum body, is slightly smaller than a 921 incandescent, yes produces a little more light. If you want a an even brighter light, look at our larger 921-17-5630 Elite Series Wedge LEDs. This is part of our Elite Series of bulbs. The PCB base also makes great contact on the first installation. Be sure to browse all of the pictures on this special retrofit light!

Warmer than incadescent

Led's generally have too harsh a light for this elder soul, have long preferred incandescent, so was pleasantly surprised to find this Warm White warmer/less harsh than the incandescents it replaced in my 1995 rv.

Lights are working

I purchased 20 of these lamps and installed them in the camper. In the past just one incandescent fixture would get the fan to turn on in the converter. Now with all the lights on in the trailer the fan doesn't turn on. It only turns on when the outside light turns on and that is still an incandescent light. I did notice that a couple of the lamps were not the warm white that most of them are but one or two are a little more blue than what I was expecting. No need to change as the lights are working and the adjacent bulb in the fixture helps tame the color down.

Pricy but worth it

I did a lot of research before I replaced every bulb inside and outside my RV. Everything I found on Amazon appeared to be cheap and low-quality with mixed reviews. Many reviews described hot-running bulbs that burn out--likely due to voltage variations from an RVs DC power. M4 LEDs are very high-quality. I've had M4 LEDs in my RV for nearly 2 years now, and they're fantastic. I would highly recommend them.

These are AWESOME!

The first thing you'll notice is the quality of the bulb. Very nice. I've heard a lot about switching over to LED bulbs, however I was a bit nervous because of the type of light output I wanted. I didn't want to blueish look, and wanted something that was easy on the eyes yet bright enough to see. The price is just right and the pics of the color of the light output makes the choice easier when you pick which one you want. Perfect to begin the move over to LED and great if you boondock too.

Boondocking for us

We replaced all of our camper's internal bulbs with these 921 natural white bulbs and am very pleased with the results. They run cool with a low amp draw. Easy to install.

Run amazingly cool!

My camper has a fan cooler on the fuse box. It would turn on as soon as a light switch came on with the old bulbs. I can have all of these on and it does not come on now! Love them. Well worth the price! Great service also.

These bulbs were perfect. The customer rep was very helpful in selecting the correct bulbs to fit my RV. Great color.

Awesome lights. Can't wait to check them out on batteries in the desert. Can't believe the difference in the amount of heat these lights generate vs. the standard lights.
